Most people never contribute they sign up for the free stuff which is fine, it does get you down some times but hey im guiltily of it at other places iv signed up just to rape and pillage some info, im sure we all probably have.
People that post here i would rather have because they want to not because they feel they have to in order to get free stuff.
